KELDAN Remote control

When I spotted this strange-looking, boxy gadget in Keldan’s booth at the Boot show in Düsseldorf, I had to inquire what it was. It turned out to be the prototype of an upcoming videolight controller with which the imagemaker can remotely adjust the output of two videolights directly from the camera housing.

Warmer waters in Ontario lakes messes with lake trout's diet

According to a new study, climate change is giving rise to changes in the diets of fishes in Ontario lakes, thereby altering the food webs there.

Researchers from the University of Guelph have discovered that the fish in Ontario lakes have been forced to forage in deeper waters due to the warmer average temperatures in the past decade. As a result, they consume prey species that are different from their normal diet, and this has led to a change in the flow of energy and nutrients in the lake.
